A digital broadcasting transmission system processes dual transport stream (TS) including multi turbo streams. The digital broadcasting transmission system includes a turbo processor to detect a turbo stream from a dual transport stream (TS) which includes a multiplexed normal stream and a turbo stream, encoding the detected turbo stream and stuffing the encoded turbo stream into the dual TS; and a transmitter to trellis-encode the processed dual TS, and to output the resultant stream, wherein the turbo processor encodes the turbo stream using a plurality of turbo processors. Accordingly, a plurality of turbo streams may be processed in parallel.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A digital broadcasting reception apparatus which receives a transport stream TS) including a normal data stream and an additional data streams stream, the apparatus comprising: a trellis decoder to perform trellis decoding of the additional data stream; an outer deinterleaver to deinterleave the trellis-decoded additional data stream; a decoder to decode the deinterleaved additional data stream; and an outer interleaver to interleave the decoded additional data stream and transmit the interleaved additional data streams to the trellis decoder.
2. The digital broadcasting reception apparatus of claim 1 , further comprising: a frame formatter to perform frame formatting of the additional data stream output by the decoder.
3. The digital broadcasting reception apparatus of claim 2 , further comprising: a symbol deinterleaver to convert the additional data stream output by the frame formatter from symbol unit to byte unit.
4. A reception method of a digital broadcasting reception apparatus which receives a transport stream (TS) including a normal data stream and an additional data stream, the method comprising: performing trellis decoding of the additional data stream, the trellis decoding being performed by a trellis decoder; deinterleaving the trellis-decoded additional data stream; decoding the deinterleaved additional data stream; and interleaving the decoded additional data stream and transmitting the interleaved additional data streams to the trellis decoder.
5. The reception method of claim 4 , further comprising: performing frame formatting of the respective decoded additional data stream.
6. The reception method of claim 5 , further comprising: converting the respective frame formatted additional data stream from symbol unit to byte unit.
